Title: Traction control system valve
Inventor: SMITH GERARD F
IPC: B60T13/68
Filed: 1993-12-14
Abstract: Abstract A valve (100), for use with a vehicle brake system (102) including an electronic control unit (ECU) (126),  including a valve body,  a regulator assembly (140)  internal  to the body,  a solenoid valve  (142) internal to the body and a single double-check valve (144) internal to the body.  The electronic control unit controls the traction control valve  (100)  during two modes of vehicle operation.   The regulator assembly (140) is in fluid communication with a pressurized air supply (104) and regulates the air supplied to the brake system during one mode of operation.  The solenoid valve (142) receives pressure-regulated air from the regulator assembly  (140)  and is controlled by the electronic control unit during the two modes of operation.   The single  double-check  valve  (144)  receives  pressure-regulated air from the solenoid valve (142) and receives pressurized air from the supply (104),  such that the double-check valve (144) allows the pressure-regulated air to flow from the solenoid valve (142) to the brake system during the one mode of operation, and allows the pressurized air to flow from the pressurized air supply to the brake system during the other mode of operation.

Title: Stratified enriched zones formed by the gas phase carburization and the slow cooling of cemented carbide substrates, and methods of manufacture
Inventor: BENNETT STEPHEN L
IPC: C04B41/87
Filed: 1994-03-10
Abstract: Processes are disclosed in which cemented carbide parts, having a wide range of initial carbon levels, and a wide range of sizes, can be carburized to a critical carbon level, and then slow cooled at various rates, to yield stratified enriched zones in the near-surface region of said parts. The enriched zones are characterized by the cobalt content decreasing, and the microhardness increasing, continuously through the enriched zones, and approaching values characteristic of the interior.      The combination of stratified enriched zones in the near surface region and the 6% binder interior provide the toughness and deformation resistance required for heavy roughing applications.      A wide variety of cemented carbides, having different compositions and WC grain sizes, can also be carburized and slow cooled using the same techniques to yield stratified binder enriched zones having the same hardness profiles and cobalt content profiles as described above.

Title: Synthetic gene libraries
Inventor: DENG SU-JUN
IPC: C12P19/34
Filed: 1994-06-06
Abstract: A method for the simultaneous randomization of multiple and specific regions of a protein is described. This method also controls the degree to which this randomization occurs.    Targeted  sequences within  a protein  are  partially  randomized  by  the  precise randomization of synthetic deoxyribooligonucleotides. Genes  encoding  proteins  are  assembled  from  the randomized oligonucleotides using a ligase reaction and are expressed on bacteriophage surfaces for selection of novel  activities.    The  method  can  be  used  for randomizing antibody complementarity determining regions or framework regions for enhancing the affinity of the mutated antibodies.  In one example, mutant single-chain antibodies,  specific for the Salmonella serogroup B O-antigen, with 100-fold better binding, relative to the wild-type, were isolated using the invention.

Title: Gas turbine vane
Inventor: PEPPERMAN BARTON M
IPC: F01D9/02
Filed: 1994-10-26
Abstract: ABSTRACT OF THE DISCLOSURE         A vane for the turbine section of a gas turbine has an airfoil portion with leading edge, center and trailing edge portions.  The leading edge portion is attached to the center portion by a dove tail joint that allows the leading edge portion to slide in the radial direction with respect to the center portion while preventing movement in the axial and circumferential  directions,  thereby  eliminating  thermal stresses created by differential thermal expansion between the leading edge portion and the remainder of the vane.   An opening in the vane inner shroud that is normally sealed by a closure plate allows the leading edge portion to be readily replaced in the event of damage.  The leading edge portion may be formed from a ceramic material and need not be supplied with cooling air.

Title: Process for structurally analyzing the genome of viral and subviral pathogens
Inventor: NU O BARBOSA GUSTAVO
IPC: C12Q1/70
Filed: 1995-02-22
Abstract: The present invention refers to a process for structurally analyzing, the genome of viral and subviral pathogens.  The process starts up with the immobilization of macromolecular structures solid phase related with the pathogen.  After the pathogen immobilization the enzymatic amplification of a fragment of its genome is carried out in the case of pathogens with  ADN genome.  When there is the case of pathogens with RNA genome, after the immobilization and before the enzymatic     amplification,    the   inverse transcription of a fragment of the pathogen genome is carried out.  The process ends with a study of the structure of the resulting products in the enzymatic amplification phase.

Title: Process for making fibre reinforced cellular cementious building materials
Inventor: BELLINGHAM RAMSAY
IPC: B28B1/52
Filed: 1995-04-03
Abstract: A process for making fibre reinforced cellular cementious building materials.  Firstly, mix separately a foam slurry and a cementious mixture containing water and random glass fibres. Secondly, combine the foam slurry with the cementious mixture in a container to form a cellular cementious slurry containing random glass fibres.   The container has a bottom with an orifice positioned adjacent the bottom.  Thirdly,  pull two parallel  spaced  layers  of  integrally  formed  glass  fibre reinforcing mesh through the mixing container filled with cellular cementious slurry and out through the orifice into a drying tray. As the reinforcing mesh passes through the mixing container it pulls along with it cellular cementious slurry. The orifice restricts the amount of cellular cementious slurry that is drawn into the drying tray, thereby serving to gauge the dimensions of the building material.  Fourthly leave the cellular cementious slurry to cure in the drying tray until the cellular cementious slurry has set thereby resulting in a cellular cementious building material having two reinforcing layers of integrally formed glass fibre mesh with random glass fibres extending between the two layers of integrally formed glass fibre mesh.
